Application filed October 17, 1911. Serial No. 655,159.

To all whom it may concern.

Be it known that LYFREDERICK E. GOLD- States, and a residentof Hamilton, in the State of .Ohio, have invented a certain new and useful Tile- Measuring Machine, of which the following is a specification.

he invention is designated for convenience, a tile measuring machine, but it is to be understood that it is capable of adaptation for measuring other. objects more or less similar to tiles and that-modifications may be made within the spirit of the invention to adapt itto different uses.

The invention also includes means for stamping characters upon the tiles in accordance with their measurements.

In the particular embodiment of the in- .vention described herein, the tiles are measured for length or width, but many of the particular mechanisms employed may be adapted with slight changes to measuring for thickness or for warpage and for stamping characters upon the tiles in accordance with such measurements.

Broadly described, the machine comprises a receptacle or feed box, feeding mechanism for forwarding the tiles one at a time from a group in the box tothe measuring device, a measuring device, and stamping or printing mechanism actuated in connection with the measuring device for imprinting designating characters upon the tiles. Preferably the machine is entirely automatic so that when a group of tiles is deposited in the box they are fed forward one at a time and 'measured, properly stamped and delivered without intervention by the attendant.

ll will now describe in detail, in connection with the accompanyng drawing, one exemplifying structure in which the invention is embodied.

Fig. 10v is a plan of the printing mechanism, the inking mechanism being omitted and Fig. 3 is a of the drive for the feeding only one type bar being shown for the sake of clearness. Fig. 11 is a side elevation of the same. Fig. 12 is a" transverse section through two of the type plungers. Fig. 13 is a longitudinal section through one of the plunger-s and its housing. Fig. 14 is a plan view of the printing slide 53 in proper relation to the type plungers to show how the latter are permitted to operate one at a time aprziording to the position ofthe printing s 1 e.

Referring first toFigs. 1 and 2, F is the frame, and B designates, as a whole, the feed box mounted at the rear end thereof. For convenience the feed box end is'designated as the rear of the machine, because the tiles are understood to be fed forward from that point to the oppositeend of themachine wlaich is designated as the-forward orfront en C designates, in general, the feeding mechanism, most of which is located below the bed of the machine. e

, The measuring and printing mechanisms are shown collectively in detail views but not identified in the assembled views except by specific reference characters.

Toward the front of the machine, as shown in Figs. 2 and 3, is a drive shaft 1, provided with driving pulley 2. This shaft cam shaft 4. Depending from the frame, as shown in Fig. 3, is a bracket 5 supporting bell crank 6 of which the horizontal arm is connected with large sprocket 7 on the cam shaft by pitman 8. The connection between the pitman and the bell crank is preferably by means of a spring'9 so that a yielding drive for the feeding mechanism is afiorded. The vertical arm of the bell crank is connected by means of 'a stud 10 with an adjustable pitman 11. Adjustment may be made by means of a telescoping joint, as at 12, or by means ofaplurality of notches 13 adapted to fit stud 10 or, in some cases, both of these adjustments the cam shaft revolves pitman 8.is moved up and down, bell crank 6 is oscillated and pitman 11 is thus given av fore and aft motion necessary for the feeding which will now be described in connection with-the feed box.

.85 is connected by sprockets and chain 3 with may be provided. As

The feed box,(Fig s. 1, 2, 4-and 5) consists J of two downwardly convergent sides 15,

open toward the rear, and a front piece 16 lllld' the passage of a single tile. At the bottom of the. box are provided longitudinal strips 18 on which the tiles are'supported. The

end piece 16 is provided with an adjustable gate 19 movably secured to the end piece by means of slots and bolts 20-. The gate is urged downward by spring 21 and its mo- 10 tion in that direction is limited by an adand in an'obvious manner, through links 37, the hooks 34 are thusdrawn downward be.-

tion of the cam shaft brings the slides, blocks and hooks back .to the rear end of the machine (as shown in Fig. 2) without engagement with the tiles and commencement of the next half rotation of the shaft again elevates the hooks and moves them forward,

and so on.

Just forward of the opening 17 and usually secured against end piece 16, is a brush (Figs. 1 and 2) which brushes the ference in length or width occurring in tiles 31s properly amplifiedto enable'the machine 5 justable screw 22. This gate fixes the ef upper faces of the tiles as they pass through 7 fective height of opening 17 and by yieldthe opening. It is. to be understood that ing upward, prevents in ury to the tiles or tiles are usually measured after they are the machine in case of jamming. Below glazed and therefore the glazed faces are lathe-bed the frame is provided. with guideusuallyarranged downward and the upper ways 25 and on these. reciprocate slides 26 faces, accordin to this arrangement, are (see Figs. 4, 5 and'6). These slides are prounglazed and 't erefore adapted to receive vided with inwardly projecting flanges 27 i the designating imprint. In cases where, fitting in grooves in blocks 28 as seen in Fig. for any reason, it is desirable to arrange the Y 20 4. Blocks 28 are transversely connected by glazed faces of the tiles upward the printing a bar 29. The blocks are'also provided with mechanism can be arranged to operate from slots 30 and through these slots passes a bar the bottom of the machine so as to print 31 which. serves to connect the slides 26. upon theunglazed faces. The blocks 28 are also connected at their Each of the described feeding actions 25 forward ends byqi bar 32 and to this bar is mbves a tile T forward to the position positively connected the pitman 11. On the shown in Fig. 1, the said tile pushing forbar 31 are piyoted'the long arms 33 of hooks ward the last measured tile. The newly 34 which extend up through longitudinal placed tile is now to be measured and slots 35 in the bed. The rear ends of the stamped as followsz'flhe measuring device 30 hooks are connected by rod 36 and this rod is shown in its essentials in Figs.'8 and 9 in I is connected with bar 29 by links 37. y which the dotted lines show a tile in measur- Tiles areplaced in the'box B in stacks, ing position.

upon the strlps. Completion of a half rotaconveniently, at one end, with a cam 60 upon the high part of the cam. The rotation of the cam shaft has, by the action of the cam, moved the actuating lever 62 so that measuring roller 47 has been moved away from-stop 49. The tile, having been placed, further rotation of the cam shaft 4 frees followen 61 from the high part of the" cam and thereupon spring 48 movesmeasuring lever 45 so that roller 47 promptly engages the tile and holds it against the stop 49. Printing slide 53 thereupon takes the position corresponding to the position of the lever and a corresponding type is caused to strike and mark the tile as will' be described. Further rotation of the cam shaft now again moves the cam lever 62 so that the measuring roller 47 is freed from the tile; the tile is moved forward; another tile is fed into position and measured, and soon.

'Above the printing slide 53 is arranged transverselyof the machine, a housing 70 (Figs. 1, 11, 12 and 13) in which are mounted a plurality of plungers 71, one for each type. Adjacent to the cam shaft is a bracket 72 supporting a pivot shaft 73 for the type bars 74. The free ends 75 of the type bars engage under the two-lobed cam 76 fixed on the cam shaft. The long arms of the type bars extend each through a slot 77 in the corresponding plunger and at the, forward end each bar carries a type 78 arranged to strike the tile when the latter is in measuring position. The bottom ends 79 of the plungers rest above theprinting slide 53. The type bars tend to move 'downward at the type ends by gravity and by the pull of springs 80. The type are inked by means of a pad 81 (see also Fig. 2) which is swung under the type when they are lifted. The type are then dropped upon the pad and;.again raised, the pad is swung aside, the type are dropped again toward the tile, and one of them prints upon the tile according to the position of the printing slide; the type are then raised; the tile isomoved forward and a new one is placed; the. type are again inked and so on.- These movements will be more particularly explained. The pad 81 (see especially Figs. 1 and 7 is carried on thelong end of lever 82 pivoted at 83and retracted by-a spring 84. The short arm 85 of thelever, is arranged at a right angle to the long arm and engages a reciprocating plunger 86 by means of a pin and slotconnection 87. Plunger 86 carries a roller engaging a cam 89 on the cam shaft. This cam s a single lobe. Cam .89 is arranged ,iiei I on the shaft so that when one of the lobes of type cam 76 is in engagement with the short ends of the typebars, the lobe of cam 89 actuates plunger 86 and swings the type pad 81 under against the pull of spring 84. The'lohe 0f',cam 89 is of'sufficient arc to maintain the pad in active position during a part of the rotation of shaft 4 until the type bars are free from the just-engaging lobe of cam 76. The type, thereupon, all drop upon the pad, this being permitted without regard to the position of printing slide 53 because the inking pad is at a much greater elevation than the tile and in this partial descending movement of the type it is not necessary for the ends 79 of the plungers 71 topass through the printing slide. By further rotation of the cam shaft,

the next lobe of cam 76 then raises the type;

shortly afterward cam follower 88 is released by cam 89; the inking pad is retracted-by its spring; further rotation of cam 76 then releases the short ends of the ty e bars from the just-engaging lobe of the cam, and the type then drop until the ends of all but one of the the printing slide 53. This engagement supports all but one of the type out of engagement with the tile. One of the plungers,-however, passes through slot 54 of the printing slide and the corresponding type drops upon the tile and prints upon itthe proper designating character. Further r0- tation of cam 76 again retracts all the type; the tile is fed forward; the inking pad is movedto, active position and so on.

plungers 71 engage As the tiles move forward from the printing mechanism they .pass over brushes 90 (Figs. land 2), which are urged upwardly by springs 91 into engagement with the tiles whereby their lower faces are brushed. The
